Nginx Proxy Manager: Custom locations don't work

[Iacov]

Create a proxy host and point it to your Jellyfin server's IP address and http port (usually 8096)

Enable "Block Common Exploits", and "Websockets Support". Configure the access list if you intend to use them. Otherwise leave it on "publicly accessible".

this does match 1:1 (i have deactived caching after your recommendation)

In the "SSL" tab, use the jellyfin.example.org certificate that you created with Nginx Proxy Manager and enable "Force SSL", "HTTP/2 Support", "HSTS Enabled", "HSTS Subdomains".

this also matches 1:1

In the "Advanced" tab, enter the following in "Custom Nginx Configuration". This is optional, but recommended if you intend to make Jellyfin accessible outside of your home.

this (and the following code block) is not in my configuration
do you recommend to add these settings? can i somehow test their effect? (i only use jellyfin in my local LAN or via selfhosted wireguard vpn)

so effectively, in my config, i have only "use" the tabs "Details" and "SSL"
